Original Lee and Turner three-colour projector, 1902.

Description

This three-colour projector is asociated with the cinematography pioneers Edward Turner and F Marshall Lee. It works by projecting three consecutive frames of film simultaneously by means of three projection lenses placed close together. Each frame of the film is projected three times, first through the upper lens, then the middle lens, and finally the lower lens. The colour is provided by a synchronised rotating three-sectored shutter bearing concentric bands of colour filters.
